I've modified your program slightly to fix your problem. Two points:1. Your main problem is that in the table SelectedTasks you have the field ID-Selected set as the primary key. ID-Selected is just the choice you make from the PossibleTasks table. It should not be a Primary Key. You need an ID set as the Primary Key with AutoValue for the SelectedTasks table. Then you can enter data.2. In your table grid a List control with a Query is better than a combo control, as the combo allows data to be added.I've attached the modified file.

You may also want to look at your Relationships - perhaps set so that when a student is deleted the corresponding selected task records are deleted?

Hope that helps to get you on your way. As Villeroy says, you'll need to add the ORB to make nice reports.

Nocton, Thank you very much! It comes very close to what I was looking for! It is very helpful for me to continue designing the base I need.Thank you very much for your help and for taking the time!
